With The Press Of A Key(HW#5) Mac OS

“your computer restarted because of a problem” is typically referred to as kernel panic and it can be caused by both software and hardware issues. If your Mac keeps restarting over and over again, you must first find the root of the problem and then fix it.

In the following lines, we will go over the most common causes for this problem and we will give you options on how to fix it so stay with us if your Mac has started restarting on its own and you have been unable to stop this loop.

“your computer restarted because of a problem press a key or wait a few seconds” loop on Catalina Macbook Pro

Most of our user base has seen this issue on OS Catalina using a Macbook Pro. Though this can occur more rarely on Mac Os Mojave. This leads us to believe that older laptops are more susceptible to this issue. Usually malware doesn’t intervene with your machine at Kernel level.

For starters, let’s go over the most likely causes for the sudden loops and restarts and 4 ways to fix it:

Vmware and lack of sufficient RAM

Using Vmware or any other virtual machine can destabilize your computers performance. Not enough virtual memory (RAM) is oftentimes the cause of many different problems and errors on Mac computers and it is perfectly possible that your Mac is restarting automatically because there isn’t enough RAM for all the processes that it is trying to run.

Outdated OC, plug-ins, or drivers

an outdated OS, driver, or plug-in on your Mac can cause conflicts and be a potential issue for any unexpected restarts.

Conflicting apps

this shouldn’t normally be happening but is still a potential reason for the Mac keeps restarting problem. If you’ve recently downloaded any apps that aren’t optimized properly and are causing conflicts with software that’s already on your Mac, this could be the cause behind the sudden restarts.

Hardware problems

lastly, you shouldn’t forget that there may be some kind of hardware issue on your Mac such as damaged or not properly connected RAM sticks. A hardware issue is a perfectly possible reason for the restarting problem you are facing.

About Kernel Panic

Kernel Panic is when your Mac’s screen goes black and an error message tells you that the computer needs to be restarted. Kernel Panic is an occurrence similar to the Blue Screen of Death for Windows computers and it can indicate lots of different problems.

Below, we will show you possible methods that you can try to fix this problem but note that, since the Kernel Panic problem may have different causes, you may have to go through all the fixing methods until you figure out which one works for you.

Fix 1: Update your OS

As we mentioned above, outdated software could be a possible reason for the sudden crashes of your Mac. This is especially likely if you haven’t installed the latest update for your macOS. Here is how you can fix this:

Open the Apple Menu and select System Preferences.
Next, open Software Update and see if there are any items available for update.
Click on the Update Now button on the latest update that is available for your system.
If you are running an older version of the macOS (for example, High Sierra or Sierra), try upgrading to macOS Catalina – the latest macOS version currently available.

Fix 2: Disconnect peripherals that may be causing the problem

Sometimes, there could be a hardware conflict between your Mac and a peripheral device you’ve connected to the computer. Something as simple as a USB mouse could be causing the sudden restarts on your Mac.

The fix for this problem is very simple – just start disconnecting all devices, one by one, testing to see if the problem still occurs after each disconnected device. This should allow you to figure out if the Kernel Panic is caused by a peripheral and which device is the one that’s problematic. Once you figure it out, just do not connect the peripheral that’s triggering the error to your Mac anymore.

Fix 3: Bypassing startup login items

It is also possible that the Kernel Panic crashes could be caused by a problem login items that prevent you from logging in to your Mac account. Here is a way you may be able to bypass this issue.

1. Start your Mac and enter your password normally but don’t immediately click on the login button.

2. Hold down the Shift button – this will stop any frozen/not-responding apps apps from starting.

3. While holding down Shift, click on the login button and this time the problematic items shouldn’t interfere with the normal functioning of the computer.

Fix 4: Reinstalling macOS

If none of the fixes you have tried so far has worked, this last resort option may resolve your computer restarted because of a problem Catalina problem. To reinstall your macOS, you need to do the following:

Hold down the Option key from your keyboard and restart your Mac.
This should get you to the Recovery screen where you must select the Reinstall macOS option.
Follow the prompts to reinstall the operating system. Note that you will need to have the macOS operating system on a bootable flash memory stick to complete the reinstall. If you don’t have that, you can try to do an Internet Recovery.
To do an Internet Recovery, shut-down your Mac, then press the Power Button to turn on your Mac and immediately after that (before your Mac loads the OS) press and hold-down the Alt/Option + Command + R (make sure you have Internet connection available).
Wait for the loading process to complete – depending on your Internet connection, this may take a while. After everything loads and you are at the recovery screen, select the Reinstall macOS option.
Follow the prompts of the installer and once the re-installation process begins, wait for it to finish. Since this might take quite a while, be sure that, if you are using a Macbook, the computer isn’t running only on batter and is instead connected to the electrical outlet via its power cord. You do not want your Mac to shut down due to low batter in the middle of the re-installation process!
Once macOS reinstalls, all that is left to do is to set set up your preferences – language, country, default Wi-Fi network, etc. Once you are done here, you can now use your Mac once again, hopefully, without experiencing the Kernel Panic loops.

To use a keyboard shortcut, press and hold one or more modifier keys and then press the last key of the shortcut. For example, to use Command-C (copy), press and hold the Command key, then the C key, then release both keys. Mac menus and keyboards often use symbols for certain keys, including modifier keys:

On keyboards made for Windows PCs, use the Alt key instead of Option, and the Windows logo key instead of Command.

Some keys on some Apple keyboards have special symbols and functions, such as for display brightness , keyboard brightness , Mission Control, and more. If these functions aren't available on your keyboard, you might be able to reproduce some of them by creating your own keyboard shortcuts. To use these keys as F1, F2, F3, or other standard function keys, combine them with the Fn key.
